Events, introduced in Adventures, and revisited in Empires, are special on-buy effects not attached to cards; players can buy Events during their Buy phase to trigger whatever the effect of the Event is, as an alternative to (or in addition to) buying cards from the supply.

Events are not Kingdom cards; including one or more Events in a game does not count toward the 10 Kingdom card piles the supply includes. In fact, Events are not considered "cards" at all; any text referring to a "card" (such as instructions to "name a card", or cost reducers changing the cost of cards) does not apply to Events. However, for reference, the Event effects and costs are printed on cards in a landscape orientation with silver frames.

There are 34 Events, any number of which may be used in a game of Dominion, though Donald X recommends not using more than two total Events, Landmarks, and Projects. When choosing a random Kingdom, the Events may be shuffled into the randomizer deck; any Events that are dealt once 10 Kingdom cards have also been dealt will be included in the game.

Adventures has 30 Kingdom cards. It also has 20 Events. It's high time we looked at some of those. Man, they're sideways.

An Event is something you can buy in your Buy phase that isn't a card. You pay your , you use up a Buy, and something happens. They don't take up Kingdom card slots; you shuffle them into your randomizer deck, but when you deal out cards, keep going until you have 10 Kingdom cards. I recommend stopping at two Events, but it's up to you.

Empires brings back Events. They were fun but I did everything I could think of to do with them in Adventures. But well, this set had new stuff; maybe that new stuff would allow for more Events? In fact of thirteen new Events, nine involve either tokens or Debt or both.

There are twenty Events. Some people no doubt have already complained that the set has six blanks. Couldn't that have been six more Events? Man. You got twenty. I didn't have a pile of great ones I cut to put in the blanks. You have to stop working on the expansions at some point and let them get released.
